Although this minor house of Grandius has existed since the Imperium's inception, it only rose to the high seat of power it now occupies sixty years into the Age of Man. It did so under the leadership of Fleurette Grandius Couture, who now serves as the house's matriarch among many other prestigious positions. The house is influential in the commerce and industry of Capitale, owning many disparate businesses there—as well as an entire production chain that allows them to manufacture airships. Most Grandian airships are designed and built by Grandius Couture's holdings.
